Thoughtful Thursday: The Cliff

[Cliff Swallow, South Cape May Meadows, NJ, May 17, 2016. Click to enlarge. Face pattern on Cliff can be variable enough to create confusion with the rare vagrant Cave Swallows - Richard Crossley and I were discussing this the other day. Pay attention to rump color, paler on Cliff.]

Regret is the worst human emotion. If you took another road, you might have fallen off a cliff. I'm content.
